Hi
As the shop is currently out of stock of the encoder magnets, has anyone found a UK supplier ? The exact dimension magnet (6x5mm) is difficult to find, I suspect that it may still work with 4 or 5mm diameter magnets? but can anyone confirm if that would cause issues
Regards,

Hi! You can use any dimension of magnet, keep in mind that thicker magnets usually mean more field strength, which can mean more immunity from field distortion (see here Designing for Magnetic Encoders — ODrive Documentation 0.6.11 documentation).
I believe we’ll be restocking the magnets within a month or two. Meanwhile, you can use e.g.:
8mm x 3mm from Guysmagnets
6mm x 3mm from Magnetstore
Those will both be lower field strength than the 6x5mm ones we sell on the shop, but that’s perfectly manageable. I’d recommend giving the aforementioned magnetic encoder design guide a close read, and the examples section is useful.
